CKY, I am starting to believe that maybe the Raid controllers are sensitive to any out of spec fsb, but that should not make a difference on the KT7a I am using, since I am only running it, non raid, with one drive. WW bios, btw.
I just feel the Abit give inconsistent results, as well. I have a Tbird out there that supposedly would not run at 1.45GHz, as I tested it on my IWill board. I tested another one for the fella, this time on my KT7a, and he still cannot get to more than 1410 on his system. 🙁
I have not modded anything. My IWill is a stock rev 1.1, non raid board, running as it came out of the box. Heck, I've not even updated the bios on it.
